Fig. 2From: A potent betulinic acid analogue ascertains an antagonistic mechanism between autophagy and proteasomal degradation pathway in HT-29 cellsFormation of AVO. Control and 2c (14.9 μM; 0–48 h) treated HT-29 cells (2.5 × 105/ml) were stained with acridine orange (1 μg/ml) for 15 min and AVO formation was measured using fluorescence microscope (60×)Back to article page
